Details
Consider not cutting Switch Grass back late fall in your garden; it holds up well in heavy snow providing winter cover for small mammals and land birds. Birds will also feed on the seeds and the dried foliage adds a splash of pale yellow to the winter landscape. Switch Grass is clump-forming and rhizomatous. It is a dominant grass of what was the vast tallgrass North American prairie.
